Description

The invention relates to ammunition, and more specifically to beam warheads containing expandable throwing blocks, the explosion of which creates a forward-directed along the axis of the projectile (grenade) beam of ready-to-use striking elements or explosive-shaped bullets (“shock nuclei”).

The warhead proposed in [1] consists of throwing blocks, each of which contains a body with an explosive charge and a fragmentation plate. Throwing blocks have the shape of parallelepipeds pivotally connected to each other, which ensures the disclosure of the warhead before undermining with the formation of a large total area of axial throwing. This design is adopted as a prototype of the invention.

The main disadvantage of the prototype is the square shape of the cross section of the projectile, which excludes its launch from launch tubes (trunks) of circular cross section, the most widely used in various types of weapons. The use of a round cross-section pallet provided in [1] leads to a decrease in the useful mass of the shell.

The present invention seeks to remedy this drawback.

The technical solution consists in the fact that the warhead of a circular cross section is made of low cylindrical sections stacked on top of one another, the bottom of which is a solid cylindrical throwing unit, and the remaining sections are composed of parts obtained by dividing the cylindrical block along radial planes, and these parts are made with the possibility of pushing them before undermining beyond the boundaries of the initial cylindrical volume of the warhead. The number of parts in one section can vary from two to four. In the future, each of these parts will be called a retractable throwing unit.

The design of the propelling devices throwing blocks may be different. The main versions of the devices are as follows:

Scheme I - with progressive pushing apart throwing blocks;

Scheme II - with the rotation of the throwing blocks around the axes parallel to the axis of the projectile.

As an example, designs with the execution of expandable cylindrical sections in two parts are considered. The invention is illustrated by drawings: figure 1 - General view of the warhead according to scheme I; figure 2 is a longitudinal section of the warhead; figure 3 - warhead with the removed throwing blocks; figure 4 is a longitudinal section of the warhead according to scheme II; 5, 6 - view of the projectile, respectively, on the rear and front sections (a - in the initial state, b - with partial extension); Fig.7 - the warhead of the circuit I in the extended state; Fig - warhead of the circuit II in the extended state.

The beam warhead, constructed according to scheme I (Figs. 1, 2, 3), contains five throwing blocks, of which the rear fixed block 1 is made in the form of a low cylinder, and the other four 2 are made in the form of half cylinders. The throwing unit consists of a housing 3 filled with a charge of explosive 4, at the front end of which a fragmentation plate 5 is mounted. Throwing blocks in the form of halves of a low cylinder (half cylinders) contain radial channels 6 of square cross section, equipped with detonators 7. Blocks in the form of half cylinders are mounted with radial channels on consoles 8 of the axial rod 9. At the front end of this rod there is a head trajectory fuse 10 with a command receiver 11. In the internal channels of the axial rod and consoles are extended charges BB 12 (or detonation cords), performing the role of detonation wiring. A thin-walled fairing 13 is placed between the fuse and the warhead. In official use and in flight until the warhead is opened, the movable throwing units are fixed by stoppers (not shown in Figs. 1-3).

The beam warhead, built according to scheme II (Figs. 4, 5, 6), contains five throwing blocks, of which the bottom fixed block 1 is made in the form of a low cylinder, and four extendable throwing blocks 14 are made in the form of half cylinders mounted on axles 15, parallel to the axis of the grenade. Crossbeams 16 are attached to the front ends of the axes, on which a fairing 17 is attached. A bottom trajectory fuse 18 is installed along the axis of the stationary throwing unit with the receiver 19 pointing outward. In the internal cavities of the axes, transfer charges BB 20 (or detonation cords) are installed; playing the role of detonation wiring. In official circulation and in flight before the disclosure of the warhead, the position of the throwing blocks is fixed by stoppers (not shown in Figs. 4-6). In figure 5, 6 throwing blocks shown without laying GGE.

Fragmentation plates of throwing blocks can be made either in the form of a single-layer set of ready-made striking elements, or in the form of a plate with meniscus depressions extruded on it, facing the vertices to the explosive charge, or in the form of plates of a given crushing.

The optimal configuration of the throwing blocks, determined by the ratio of the diameter of the section to its height (thickness), was calculated. According to the theory of the active mass of the explosive charge by KP Stanyukovich [2], the fraction of the chemical energy of the explosive charge, which transfers into the kinetic energy of the fragmentation plate, increases with this ratio. Given the sliding conditions of the detonation wave on the contact surface of the "explosive charge - fragmentation plate", the ratio of the diameter of the section to its height should be within 3 ... 5.

Tufted warheads are mainly designed for reactive caliber ammunition of various types of weapons, including:

- hand grenade launchers;

- barrel systems for active protection of armored vehicles, helicopters, various ground objects;

- multiple launch rocket systems;

- air missiles of the air-to-air and air-to-ground class.

The trajectory fuse can be either temporary or rotational, or non-contact, or command type.

Grenade action

In official circulation and in flight before the disclosure of the warhead, the position of the throwing blocks is fixed with the help of stoppers. Before firing into the head fuse 10 through the receiver 11 or the bottom fuse 18 through the receiver 19 using a contact or non-contact method, the flight time setting is entered before the warhead is triggered. When approaching a grenade at the calculated opening point, the fuse gives a command to turn off the stoppers that fix the position of the throwing blocks. Further action in schemes I, II is different.

Scheme I

Under the action of centrifugal forces, the semicylinders diverge in opposite directions (Fig. 7). In this case, the end face of the fixed throwing unit 1. After the warhead is opened, the fuse gives a command to detonate the detonation wiring, which ensures the detonation of all five throwing blocks with the formation of the total axial beam of the GGE or explosive bullets.

Scheme II

After turning off the stoppers, a pyrotechnic device is triggered (not shown in FIGS. 4-6), causing the initial displacement of all four sliding throwing units. Then, under the action of centrifugal forces, the throwing blocks diverge in radial directions, rotating around the axes 15. At the same time, the end face of the stationary throwing block 1. After the full opening of the warhead (Fig. 8), the bottom fuse 18 gives a command to detonate the fixed block, after which the detonation of the internal charges of the axes 20 are bred by throwing blocks 14 with the formation of the total axial beam of the GGE or explosive bullets.

A feature of both schemes is the propagation of detonation in sliding throwing units in radial directions, which leads to the formation of a peripheral zone of damage in the beam section. The central lesion zone is formed mainly by a fixed propelling unit.

The technical result is an increase in the combat effectiveness of beam caliber rocket-propelled grenades.
